pdb_mysql.c prints out connection message twice. Example: When adding a user
with pdbedit, the line that a connection to MySQL server X with username Y has
occured is printed out twice.
Maybe (not filing this as a new bug report at the moment) it would also be
possible to omit this line completely for security purposes. I know, it's just a
line in the .c file I could remove, but maybe an option in smb.conf would be
valueable. :-)
